Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bathroom technology, specifically a siphon toilet. Background Technology
[0002] Toilets are ubiquitous bathroom products in daily life and are increasingly widely used. In order to achieve a better odor-proof effect, a water seal needs to be installed in the waste storage area of the toilet. Furthermore, national industry standards have clear requirements for the minimum water seal standard.
[0003] Toilets with jet nozzles at the bottom are a common type of toilet on the market. They flush by expelling waste through these nozzles. However, these toilets often produce significant noise during flushing, disturbing others. While eliminating the jet nozzles and using a siphon system for waste removal could effectively solve the flushing noise problem, existing siphon toilets also have certain drawbacks.
[0004] like Figure 1 As shown, an existing siphon toilet includes a toilet body 1 with an overall height of H1. A drain pipe 2 connects to the bottom of the toilet body 1. The distance between the water surface of the drain pipe 2 and the bottom of the toilet body 1 is h1, where h1 / H1 is 0.63. The water surface of the drain pipe 2 and the water surface inside the toilet body 1 are on the same plane. During flushing, when the distance between the rising water surface in the toilet body 1 and the bottom of the toilet body 1 is X1, a siphon effect is created to expel waste.
[0005] The current distance h1 is relatively long, which means that it takes a long time for the siphon to form during the water rise process inside the toilet body 1. As a result, the water rise surface that needs to form a siphon during flushing is also relatively high, and the water rise surface area inside the toilet body 1 is also relatively large. This leads to a larger area of waste spreading with the water rise surface during flushing, and floating waste may not be completely flushed, affecting the sewage discharge performance of the toilet body 1. Utility Model Content
[0006] To address the problems mentioned above, this utility model provides a siphon toilet. With a reduced drain pipe height, the time required to form a siphon during flushing is shorter than in existing technologies. The siphon is formed earlier in this application, and the height of the water level in the toilet body is also reduced compared to existing technologies when the siphon is formed during flushing. This reduction in the water level decreases the area of the water surface in the toilet body, reducing the area of waste diffusion during flushing and increasing the likelihood of waste removal, thereby improving the toilet's flushing performance.
[0007] This utility model provides a siphon toilet, including a toilet body, the toilet body being connected to a drain pipe, the drain pipe being configured with varying heights to reduce the distance between the water surface of the drain pipe and the bottom of the toilet body.
[0008] By adopting the above technical solution, after the height of the sewage pipe is reduced, the time required to form a siphon during flushing is shorter than that in the prior art. The siphon is formed earlier in this application, and the height of the water surface in the toilet body is also reduced in the same way as in the prior art when the siphon is formed during flushing. After the water surface is reduced, the corresponding water surface area in the toilet body is reduced, and the diffusion area of sewage with the water surface is also reduced during flushing, which increases the possibility of sewage being discharged and thus improves the sewage discharge performance of the toilet body.
[0009] Furthermore, the toilet body is provided with a brush hole for flushing.
[0010] By adopting the above technical solution, and using the scrubbing hole for flushing, the design of the bottom spray hole in the toilet body is eliminated, which greatly reduces the noise of the toilet body when flushing.
[0011] Furthermore, the toilet body is provided with a buffer cavity that communicates with the brush hole, and the width of the buffer cavity gradually narrows towards the brush hole.
[0012] By adopting the above technical solution, when the washing water enters the buffer cavity through the water outlet, the width of the buffer cavity near the water outlet is larger, which can buffer the impact force of the washing water and reduce the possibility that the washing water will easily splash to the outside of the toilet body due to the large impact force when it flows out of the washing hole.
[0013] Furthermore, the toilet body is a wash surface, and the wash holes are flat and fitted to the wash surface.
[0014] By adopting the above technical solution, the brushing hole is flat and fits the brushing surface, so that the brushing water flows out flat and fits the brushing surface.
[0015] Furthermore, the brushing surface is bounded by the central axis of the toilet body, and the slope of the side of the brushing surface near the brushing hole is steeper than that of the other side.
[0016] Furthermore, the connection between the brushing surface and the bottom of the toilet body is a peg opening, and the area of the brushing surface near the central axis of the toilet body forms a recessed area, the width of which gradually decreases from the front end of the toilet body towards the peg opening.
[0017] By adopting the above technical solution, after the washing water leaves the brush hole and enters the brush surface, it is diverted when it reaches the recessed area at the front of the toilet body. Most of the water is guided by the brush surface and the recessed area to the peg opening, while a small portion of the water flows downwards along the circumference of the brush surface to complete the washing of the brush surface. The width of the recessed area gradually decreases from the front of the toilet body towards the peg opening, giving the washing water a certain impact force when it reaches the peg opening. This guides the washing water to tumble up and down within the peg opening, better carrying away waste into the sewage pipe and improving the toilet body's sewage discharge capacity.
[0018] Furthermore, a section of the soiled area at the bottom of the toilet body is the inlet section, and a protrusion is provided at the junction of the bottom of the toilet body and the inlet section.
[0019] By adopting the above technical solution, the protrusion facilitates the sliding of fecal matter into the bottom inlet section for storage after it passes through the protrusion.
[0020] Furthermore, the angle between the central axis of the inlet section and the horizontal plane is between 35° and 55°.
[0021] By adopting the above technical solution, the angle between the central axis of the inlet section and the horizontal plane is 35° to 55°, which helps the dirt to fall smoothly after passing the protrusion and accumulate in the bottom dirt storage area near the sewage pipe inlet. The scrubbing water can fully cover and push the dirt into the sewage pipe for discharge.
[0022] Furthermore, the sewage pipe is equipped with a displacement device body.
[0023] By adopting the above technical solution, the height of the sewage pipe is reduced, which restricts the size of the sewage pipe layout. Due to the requirements of the process structure, a displacement device body is installed at the outlet of the sewage pipe to solve the problem of the limited size of the sewage pipe layout.
[0024] Furthermore, the overall height of the toilet body is H1, the distance between the water cover of the sewage pipe and the bottom of the toilet body is H2, and the ratio of H2 to H1 is between 0.5 and 0.6.
[0025] By adopting the above technical solution, the distance H2 between the water seal of the sewage pipe and the bottom of the toilet body is reduced compared with the prior art, while the setting of the distance H2 still meets the standard requirements for the minimum water seal.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0027] (1) After the height of the sewage pipe is reduced, the time required to form a siphon during flushing is shorter than that in the prior art. The siphon is formed earlier in this application. When the siphon is formed during flushing, the height of the water surface in the toilet body is also reduced compared to the prior art. After the water surface is reduced, the water surface area in the toilet body is reduced. When flushing, the diffusion area of the sewage with the water surface is also reduced, which increases the possibility of sewage being discharged and thus improves the sewage discharge performance of the toilet body.
[0028] (2) The toilet body eliminates the bottom spray hole design and greatly reduces the noise of the toilet body when flushing by using the brush hole for flushing.
[0029] (3) After the washing water leaves the brush hole and enters the brush surface, the water is divided when it reaches the recessed area at the front of the toilet body. Most of the water is guided by the brush surface and the recessed area to the peg opening, while a small portion of the water flows downward along the circumference of the brush surface to complete the washing of the brush surface. The width of the recessed area gradually decreases from the front of the toilet body to the side closer to the peg opening, so that the washing water in the recessed area has a certain impact force when it reaches the peg opening, guiding the washing water to turn up and down in the peg opening, which can better carry the dirt into the sewage pipe and improve the sewage discharge capacity of the toilet body.

[0042] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0043] The following is in conjunction with the appendix Figure 2 To be continued Figure 10 The present invention will be described in detail with specific embodiments.
[0044] like Figures 2 to 5 As shown, this utility model provides a siphon toilet, including a toilet body 1 with an overall height of H1. A drain pipe 2 is connected to the bottom of the toilet body 1, and the toilet body 1 has a brush hole 11 for flushing. The drain pipe 2 is lowered, and the distance between the water surface of the drain pipe 2 and the bottom of the toilet body 1 is H2, where H2 / H1 is between 0.5 and 0.6, preferably 0.55. During flushing, the distance between the siphon-induced water surface and the bottom of the toilet body 1 is Y1.
[0045] In this application, the distance H2 between the water seal of the sewage pipe 2 and the bottom of the toilet body 1 is reduced compared to the prior art, while the setting of the distance H2 still meets the standard requirements for the minimum water seal.
[0046] After the height of the sewage pipe 2 is reduced, the time required to form a siphon during flushing is shorter than that in the prior art. The siphon is formed earlier in this application, and the height of the water surface in the toilet body 1 is also reduced in the same way as in the prior art when the siphon is formed during flushing. After the water surface is reduced, the water surface area in the toilet body 1 is reduced, and the diffusion area of sewage with the water surface is also reduced during flushing, which increases the possibility of sewage being discharged and thus improves the sewage discharge performance of the toilet body 1.
[0047] In this application, the design of the bottom spray hole in the toilet body 1 has been eliminated, which greatly reduces the noise of the toilet body 1 when flushing while still being able to discharge sewage.
[0048] The sewage pipe 2 is integrally formed with the toilet body 1. Due to the reduced height of the sewage pipe 2, the layout size of the sewage pipe 2 is limited. Due to process and structural requirements, in this application, the sewage pipe 2 is equipped with a displacement device body 3. The sewage pipe 2 is inserted into the water inlet of the displacement device body 3. The problem of the limited layout size of the sewage pipe 2 is solved by setting the displacement device body 3. The sewage in the sewage pipe 2 is discharged after passing through the displacement device body 3.
[0049] like Figure 6 As shown, the toilet body 1 is provided with a water outlet 12, which is connected to the brush hole 11. The space between the brush hole 11 and the water outlet 12 is a buffer cavity 121. The width of the buffer cavity 121 gradually narrows from the side closer to the water outlet 12 to the side closer to the brush hole 11. When the brushing water enters the buffer cavity 121 through the water outlet 12, the width of the buffer cavity 121 is larger on the side closer to the water outlet 12, which can buffer the impact force of the brushing water and reduce the possibility that the brushing water will easily splash to the outside of the toilet body 1 due to the large impact force when it flows out of the brush hole 11.
[0050] The buffer cavity 121 gradually narrows in width towards the brush hole 11, which plays a role in rectifying the flow of the brush water. The brush water flows out from the brush hole 11 to flush the toilet body 1.
[0051] The inner wall of the toilet body 1 is a scrubbing surface 13, and the scrubbing hole 11 is flat and fits the scrubbing surface 13 so that the scrubbing water flows out flat and fits the scrubbing surface 13.
[0052] like Figures 7 to 9 As shown, the scrubbing surface 13 is asymmetrically positioned about the central axis of the toilet body 1. With the central axis as the boundary, the left side of the scrubbing surface 13 has a steeper slope than the right side, and the left side is closer to the scrubbing hole 11. To better illustrate the left-right slope relationship of the scrubbing surface 13, Figure 7 The sections a, b, c, d, and e along the vertical direction are labeled. Figure 8 China Figure 7The slopes corresponding to sections a, b, c, d, and e are shown. The connection between the scrubbing surface 13 and the bottom of the toilet body 1 is a peg opening 15. The area of the scrubbing surface 13 near the central axis of the toilet body 1 forms a recessed area 14. The width of the recessed area 14 gradually decreases from the front end of the toilet body 1 towards the peg opening 15.
[0053] After the washing water leaves the brush hole 11 and enters the brush surface 13, it is split when it reaches the recessed area 14 at the front end of the toilet body 1. Most of the water is guided by the brush surface 13 and the recessed area 14 to the peg opening 15, while a small portion of the water flows downward along the circumference of the brush surface 13 to complete the washing of the brush surface 13.
[0054] The width of the recessed area 14 gradually decreases from the front end of the toilet body 1 towards the side near the peg opening 15, so that when the washing water in the recessed area 14 flows to the peg opening 15, it has a certain impact force, which guides the washing water to tumble up and down in the peg opening 15, so as to better carry the dirt into the sewage pipe 2 and improve the sewage discharge capacity of the toilet body 1.
[0055] The bottom section of the toilet body 1, which serves as the waste storage area, is the inlet section 16. A protrusion 17 is provided at the junction of the bottom of the toilet body 1 and the inlet section 16. The protrusion 17 facilitates the sliding of feces into the bottom inlet section 16 for storage. The angle between the central axis of the inlet section 16 and the horizontal plane is between 35° and 55°, preferably 45°. This angle helps the waste to smoothly fall through the protrusion 17 and accumulate in the bottom waste storage area near the inlet of the drain pipe 2. The washing water can then fully cover and push the waste into the drain pipe 2 for discharge.
[0056] The implementation principle of the siphon toilet provided by this utility model is as follows: After the height of the sewage pipe 2 is reduced, the time required to form a siphon during flushing is shorter than that in the prior art. The siphon is formed earlier in this application. When the siphon is formed during flushing, the height of the water surface in the toilet body 1 is also reduced compared to the prior art. After the water surface is reduced, the corresponding water surface area in the toilet body 1 is reduced. When flushing, the diffusion area of sewage along the water surface is also reduced, which increases the possibility of sewage being discharged and thus improves the sewage discharge performance of the toilet body 1.
[0057] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
